Using the SQL schema tool

This package contains the tooling for cadence sql operations. The tooling itself is agnostic of the storage engine behind the sql interface. So, this same tool can be used against, say, OracleDB and MySQLDB

For localhost development

SQL_USER=$USERNAME SQL_PASSWORD=$PASSWD make install-schema-mysql

For production

Create the binaries

  • Run make bins
  • You should see an executable cadence-sql-tool
  • Cadence officially support MySQL and Postgres for SQL.
  • For other SQL database, you can add it easily as we do for MySQL/Postgres following our code in sql-extensions

Note: The binaries can also be found in the ubercadence/server docker images

Do one time database creation and schema setup for a new cluster

  • All command below are taking MySQL as example. For postgres, simply use with "--plugin postgres"
./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql create-database --db cadence
./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql create-database --db cadence_visibility

./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence setup-schema -v 0.0 -- this sets up just the schema version tables with initial version of 0.0
./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence update-schema -d ./schema/mysql/v57/cadence/versioned -- upgrades your schema to the latest version

./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence_visibility setup-schema -v 0.0 -- this sets up just the schema version tables with initial version of 0.0 for visibility
./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence_visibility update-schema -d ./schema/mysql/v57/visibility/versioned  -- upgrades your schema to the latest version for visibility

Update schema as part of a release

You can only upgrade to a new version after the initial setup done above.

./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence update-schema -d ./schema/mysql/v57/cadence/versioned -v x.x -y -- executes a dryrun of upgrade to version x.x
./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence update-schema -d ./schema/mysql/v57/cadence/versioned -v x.x    -- actually executes the upgrade to version x.x

./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence_visibility update-schema -d ./schema/mysql/v57/cadence/versioned -v x.x -y -- executes a dryrun of upgrade to version x.x
./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence_visibility update-schema -d ./schema/mysql/v57/cadence/versioned -v x.x    -- actually executes the upgrade to version x.x
